WebCryptographically secure hashes usually work on bitstrings of arbitrary length and output a fixed length bitstring. The secure part is being collision resistant and preimage resistant, so that you have a practical oneway function, and those are the properties you want for "scrambling"..

Developed by the U.S. government in the 1990s, SHA-1 used techniques like those of MD5 in the design of message-digest algorithms. But SHA-1 …
Hash functions can be used to build other cryptographic primitives. For these other primitives to be cryptographically secure, care must be taken to build them correctly. Message authentication codes (MACs) (also called keyed hash functions) are often built from hash functions. HMAC is such a MAC. Just as block ciphers can be used to build hash functions, hash functions can be used to build bl… WebIn cryptography, a message authentication code ( MAC ), sometimes known as an authentication tag, is a short piece of information used for authenticating a message. In other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed.
